Here is a video of the XTIDE settings that seem to be best for the Sega TeraDrive. Please note I have used a slightly less than current version 2.0.0b1 instead of 2.0.0b2. As long as it works I do not feel the urge to upgrade just yet… Maybe once it is not a beta I will. The EEPROM BIOS dump for the TeraDrive can be found on the File Server.
More information on XT-IDE, also known as XTA can be found here.
